Ubumenyi bwumuti udasanzwe wa urea

Ibinyabiziga urea kandi bakunze kuvuga ko urea yubuhinzi ifite itandukaniro. Ibinyabiziga urea ni ukugabanya imyuka ya azote na hydrogène ihumanya itangwa na moteri ya mazutu, kandi ikagira uruhare mu kurengera ibidukikije. Ifite ibisabwa bihuye neza, bigizwe ahanini na urea yera cyane n'amazi ya deioni. Kimwe mu bimenyetso byingenzi byerekana ubuziranenge ni urwego rwo kugenzura umwanda. Ibice, ioni ibyuma, imyunyu ngugu nibindi byanduye muri urea ni byinshi, kandi ingaruka ziragaragara cyane. Iyo urea itujuje ibyangombwa byongeweho, bizaganisha ku kunanirwa nyuma yo gutunganywa, ndetse bitange ingaruka mbi zica bidasubirwaho nyuma yo gutunganywa. Kandi ku bihumbi mirongo yuan nyuma yo gutunganywa, cyangwa guhitamo ikirango urea cyasabwe nuwabikoze.

Ni ibihe bintu biranga?

Weichai igisubizo cyihariye cya urea cyujuje ubuziranenge mpuzamahanga ISO22241-1, Ubudage busanzwe DIN70070 hamwe na GB29518 yigihugu, ubuziranenge bwabatangabuhamya.

Ingaruka yibicuruzwa byimpimbano kandi biri hasi: igisubizo cyibisubizo bya urea ntoya ntabwo bigera kurwego rusanzwe, ubuziranenge ntibuhagije, umwanda mwinshi muri urea, byoroshye korohereza, guhagarika urea nozzle, muriki gihe, urea nozzle irashobora kuba yakuweho, ashyushye kandi atetse kugirango aseswe. Nyamara, gukoresha igihe kirekire gukoresha urea yimodoka itujuje ubuziranenge bwubugenzuzi buteganijwe na leta bizagabanya igipimo cya NOx ihinduka, bigabanye imikorere nubuzima bwa catalizator, kandi byangiza byimazeyo sisitemu ya SCR, bikavamo post idasubirwaho -kunanirwa.

Isuku nziza

Kugirango ugere kuri ultra-high urea ibisabwa byujuje ubuziranenge, igisubizo cyihariye cya urea cya Weichai kigomba kunyura muburyo butandukanye bwo kuyungurura no kuyungurura neza mubikorwa, kandi ibikoresho byo gupakira bigomba kuba bitarimo ivumbi. Ihame ryibanze ryakazi rya sisitemu ya SCR: umuyaga winjira mu muyoboro uva muri turbine ya charger. Muri icyo gihe, n’ishami ryatewe inshinge za urea zashyizwe muri DPF, ibitonyanga bya urea bigira hydrolysis na pyrolysis reaction ya gaze ya gaze yubushyuhe bwo hejuru, itanga NH3 isabwa, NH3 igabanya NOx kuri N2 ikorwa na catalizator. Muri sisitemu yo kugabanya SCR, kwibanda kumuti wa urea nikimwe mubintu byingenzi, ariko cyane cyangwa kwibanda cyane ntibishobora kunoza imikorere ya NOx, ariko bizatera kunyerera kwa amoniya no gushiraho amoniya yanduye ya kabiri.

Guhinduka cyane

Hamwe n'umuti udasanzwe wa urea hamwe na 32.5% nkibikoresho bigabanya; Nkibisanzwe bisanzwe bya sisitemu ya SCR nyuma yubuvuzi, gukoresha urea bingana na 5% byamavuta yakoreshejwe. Fata ubushobozi bwa 23Lde urea tank nkurugero, mileage irashobora kugera kuri kilometero 1500-1800.

Urea ongeramo amazi: akenshi umuntu abaza niba urea ishobora kongeramo amazi yubutare, amazi yatetse neza nibindi bintu. Ibi ntibishoboka rwose, hariho umwanda mwinshi mumazi ya robine, kure cyane yukureba amaso yacu. Kalisiyumu, magnesium, sodium nibindi bintu mumazi ya robine namazi yubutaka byoroshye gukora ibintu bikomeye, bityo bikabuza urea nozzle, biganisha kumakosa nyuma yo gutunganywa. Amazi yongewe muri urea, arashobora gusa kuba amazi yimana. Urwego rwamazi ya urea rugomba kubikwa hagati ya 30% na 80% yubunini bwikigega cya urea. Ububiko bwa Urea: Umuti wa Urea ugomba kubikwa mu kintu gifunze ahantu hakonje, humye, kure ya okiside ikomeye. Iyo wuzuza, nko mu kigega cya urea guta imyanda ya urea, kandi bikabyara ibidukikije. Ibikoresho byo kuzuza umwuga birasabwa.

Icyitonderwa cyo kuzuza urea: urea igisubizo cyangirika kuruhu. niba uruhu cyangwa amaso byongeyeho, kwoza amazi vuba bishoboka; niba ububabare bukomeje, nyamuneka saba ubufasha kwa muganga. Niba umize utitonze, ibuza kuruka, shaka kwivuza vuba
